The advantages of aluminium windows are significant.
They are available in a range of colours and finishes, but black has proven to be one of the most popular choices with our customers. Why? It looks the part, that’s for sure – on the right home or premises, black windows can contrast beautifully with brickwork, setting your property apart from those nearby.
Both modern and historic buildings can benefit from black aluminium windows – and they can transform any property from staid to striking. To help you get inspired, here are some installations we’ve recently completed…
New windows represent a significant investment for any property owner, so it’s vital that high-quality frames are fitted. It’s for this reason that we’re very selective about what we supply here at Klosen.

Cortizo is one of the world’s most renowned manufacturers of aluminium windows and doors. Based in Spain, the company has led the industry for many years, constantly innovating and refining its impressive range of products.
Although they’re extremely well-built and boast exceptional efficiency, it’s the stunning design of Cortizo that really set them apart.
Senior Architectural Systems is a British company with a history dating back over 30 years, making it one of the nation’s leading suppliers of aluminium windows and doors.
Located in Doncaster, the company is one of the most innovative and forward-thinking around; it was the first to incorporate a polyurethane foam thermal barrier into its designs and the first to offer powder coated finishes with a no-quibble guarantee.
As one of Cambridgeshire and London’s premier suppliers of black aluminium windows, we’ve worked on a whole host of exciting projects over the years. One of the stand-outs was this stunning dream home, as featured on Grand Designs in 2021.
We were approached by the owners to install a number of Cortizo designs and were delighted by the end result – as were they! We’ve been involved with a number of other high-profile projects too – why not take a look?
Based in Market Deeping, Lincolnshire, we cover towns and cities within a 60-mile radius, including the entirety of Cambridgeshire and Lincolnshire. Areas we regularly visit include Peterborough, Bourne, Stamford, Huntingdon and London.
Struggling to decide whether or not black is the right colour choice for your home or business premises? Our windows are available in hundreds of alternative RAL colours, so there’s bound to be one that you fall in love with.
Every installation is a little different, so we can’t list approximate prices. Happily, it’s very easy to get a quote on our website, or you can pick up the phone and call us if you prefer.
On average, our lead times are currently five to six weeks from initial enquiry to installation.
